Description

Technical Field

[0001] This utility model relates to the field of heat energy exchange equipment technology, and in particular to a steam generator. Background Technology

[0002] A steam generator is a device that uses fuel (such as natural gas, oil, electricity, etc.) or other energy sources (such as waste heat) to heat water and thus produce steam.

[0003] In the existing technology, steam generators use carbon steel tube bundles and mechanical control valves, and use heat transfer oil or molten salt as the heat transfer medium. Such steam generators have the characteristics of robust structure, simple maintenance and strong anti-interference ability, but their heat transfer efficiency is low and cannot meet the increasingly high requirements of modern industry and production for steam generators.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0018] The present invention will now be described in further detail with reference to the accompanying drawings: The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0019] In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," etc., should be interpreted broadly.

Example

[0021] like Figure 1-3As shown, this application discloses a steam generator, comprising a steam generator body 10, two heat medium pumps 20, a first multi-stage water supply pump 30, a second multi-stage water supply pump 40, a softened water tank 50, and a raw water tank 60. The inlets of the two heat medium pumps 20 are connected to an external heat medium pipeline network, and the outlets of the two heat medium pumps 20 are connected to the heat medium inlet of the steam generator body 10. The heat medium outlet of the steam generator body 10 is connected to the heat medium inlet of the softened water tank 50, and the heat medium outlet of the softened water tank 50 is connected to the external heat medium pipeline network. The water inlet of the first multi-stage water supply pump 30 is connected to the water outlet of the softened water tank 50. The water outlet of water pump 30 is connected to the water inlet of the steam generator body 10; the water outlet of the second multi-stage water supply pump 40 is connected to the water inlet of the softened water tank 50, and the water inlet of the second multi-stage water supply pump 40 is connected to the water outlet of the raw water tank 60, the water inlet of the raw water tank being connected to the raw water network; the external heat medium, driven by the heat medium pump, flows through the steam generator body to transfer the main heat to the water, turning it into steam, and then flows through the softened water tank to preheat the makeup water using waste heat, finally returning to the external network. The raw water is sent to the softened water tank for treatment by the second multi-stage pump, and then pumped into the steam generator body by the first multi-stage water supply pump under high pressure, completing the entire process of makeup water, preheating, evaporation, and steam generation. The cooled heat medium does not return directly to the external network, but first enters the softened water tank to utilize this waste heat to preheat the softened water in the softened water tank, improving the thermal efficiency of the entire system and saving energy.

[0022] Specifically, a thermometer 11 is provided on the top of the steam generator body 10 to measure the temperature of the steam inside the steam generator body.

[0023] Specifically, a pressure gauge 12 is provided on the top of the steam generator body 10 to display the steam pressure inside the steam generator body.

[0024] Specifically, a steam outlet 13 is provided on the top of the steam generator body 10, and the steam generated by the steam outlet is connected to a steam pipe through this outlet and delivered to the point of use.

[0025] Specifically, the steam generator body 10 is equipped with a high-level gauge 14 and a low-level gauge 15 at one end for monitoring and controlling the liquid level inside the steam generator body. The high-level gauge is connected to the upper part of the steam generator body to determine the upper limit of the liquid level, and the low-level gauge is connected to the lower part of the steam generator body to determine the lower limit of the liquid level. This allows operators to observe the actual liquid level inside the steam generator body in real time, ensuring that the liquid level remains within a safe "high-low" range.

[0026] Specifically, a drain port 16 is provided at the lower part of the steam generator body 10 for periodically removing scale and suspended matter accumulated at the bottom of the steam generator body.

[0027] Specifically, an observation hole 17 is provided on the top of the steam generator body 10, which is used to enter the interior or observe the internal condition when the equipment is stopped, and to carry out maintenance and clean up debris.

[0028] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high heat transfer efficiency, and strong practicality.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
